Desktop virtualization has a new form factor for delivery, the smartphone, thanks to Israel-based Ceedo Technologies, which today announced its Ceedo Mobile initiative at the TechCrunch40conference in San Francisco.The initiative holds promise in enabling road warriors to carry enterprise applications and data on smartphones and then access those assets as needed through a virtualized environment that boots automatically when their mobile devices are hooked up to a host PC via USB.Ceedo Mobile leverages the PC as an interface between worker and phone, thereby tapping the PC’s connectivity and RAM. Moreover, all activities performed through the virtualized environment are cached to the mobile device’s flash memory, enabling workers to eject the device when finished and leave no trace on the host PC. The solution currently works only with Windows. Although bundling virtualized applications on USB flash drives is nothing new, doing so on the flash drive of a smartphone opens up the portable virtualized app environment model to compelling possibilities. Enabling mobile workers to perform and cache lightweight tasks on phones and leverage the PC environment in a completely secure manner when their work requires heavier resources, such as when a sales order must be processed, will surely prove enticing to today’s increasingly mobile enterprises.
